Agent Plugins 0.14.8

b10x-harness joins the catalog, and b10x chooses a prebuilt archive only where one exists for
the machine.

• catalog.json: b10x-harness (the Beyond10x agent loop that Metaharness's b10x adapter runs)
  is an optional binary of aep, installed with b10x install b10x-harness. It runs on Linux only:
  a new platforms field on a catalog binary keeps b10x from planning it elsewhere.
• b10x reads which targets the newest release's SHA256SUMS lists and chooses prebuilt only when
  this machine's target is among them; otherwise cargo, or a warning that names the target. A
  release with an archive for some machines no longer sends the others to a download that fails.
• b10x install <cli> follows the same default. Since 0.14.7 it still chose cargo whenever cargo
  was on PATH, although its help and the docs said prebuilt.
• aep:init: metaharness is optional in the plan and installed with b10x install metaharness;
  the skill said b10x init aep offers it.
• Docs name b10x-harness beside metaharness.
